Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional spectroscopic methods are used, then measurement can be performed, but signal-to-noise ratio is insufficient and detection limits are high
Solution Approach 1:
The patent divides the measurement system into multiple parallel detection channels, each detecting at different wavelengths or spectral regions. This segmentation allows simultaneous measurement of multiple metabolites with reduced noise in each channel, improving overall detection limit and signal-to-noise ratio.
Solution Approach 2:
The patent combines multiple detection signals from parallel measurements into a unified analytical result. By merging data from multiple wavelengths and detection channels, the system achieves enhanced signal-to-noise ratio and improved detection limits through signal processing and integration.
2Measurement precision
If larger sample sizes are used, then measurement accuracy can be improved, but patient invasiveness and discomfort increase
Solution Approach 1:
The patent segments the sample analysis into multiple parallel measurement channels that can process smaller individual sample portions. This allows accurate metabolite detection using minimal blood or tissue samples, reducing patient invasiveness while maintaining measurement accuracy through multi-channel data integration.
3Productivity
If conventional single-point measurement is used, then device complexity is lower, but measurement time and productivity are reduced
Solution Approach 1:
The patent implements multiple parallel measurement points or detection channels that operate simultaneously. This segmentation enables concurrent measurement of multiple metabolites or spectral regions, significantly increasing measurement productivity and speed while managing device complexity through modular parallel architecture.
4Measurement precision
If standard light sources are used, then device cost is lower, but resonance frequency optimization is insufficient
Solution Approach 1:
The patent optimizes light source parameters by tuning wavelengths to match resonance frequencies of specific metabolites or molecular bonds. This parameter optimization enhances measurement precision and detection sensitivity. The system manages complexity through automated wavelength tuning and calibration procedures.
